To ALL WHOM rr MAY ooNcERN:

Be it known that we, E. H. MERRILL a`nd H. E. MERRILL, of Akron, in the county of Summit, and State of Ohio, have invented certain Anew and useful Improvements in the Mode of Making Bottles, &c.,'of Clay; and we do lherebydeclarel that the following is a full and complete description of the same, reference being had to the accompanying drawings making a part of this specification, in whichn Figure 1 is a `side view of the apparatus.

Figure 2 is an end view.

Figure 3 is a view of the top.

Figures 4 and 5, detached sections. v

Lik'e letters of reference refer to like partsin the several Views,-

A, fig. 1, represents-the mould iin which the bottle is formed. This mould is constructed in three sections, A B O, iig. 2. Section C is fixed to the table or stand D, whereas the ltwo side sections are connected to the third by a hinged joint, E, so that the mould can be opened for the purposel of removing the bottle.

The two jointed' sections, when closed, are secured to each other by clamps, consisting of the eccentricroller F, a detached View of which is shown 4in fig. 5, journalled in the adjusting-stays a, and by which said roller is connectedto'the bar G. This bar, as will be seen, is journalled to one sectionoi` the mould in bracketstays H, attached thereto by the screw-bolts b. u l

By this device the twosections of the mould, `when closed, are easily and rmly locked together, as shown in g. 2, thus: l

Let it be supposed that the eccentric-roller andv stays a are turned up -to the position indicated by the` dotted-lines e, fig. 2. In this position of the clamp the two sections of the mould A B can be thrown open. Now, on turning Vthe clamp down'frorn its vertical position to that shown in iig. 2, the roller F is slipped over the ends of the cleats I, which are seen to project slightly above the top 0` the sections. This being donefthe two sections are then drawn tight together, by giving the roller a turn by means offthe handle J. This turning of the roller will bring its eccentric side d, iig. 5, against'the. cleats, thereby binding the two sections together.

v On a reverse turning of the roller; the clamp is'loosened by bringing the concentric side, el', of the roller towards the cleats. The clamp can then be thrown up to the-'position first indicated, and the mould opened, as above said. Y i i By means of the adjusting-stays a the distance between the bar and roller can be lengthened or shortened up, and Athereby adjust the clamp toits place and-purpose. t

O,4fig. 2, is a disk,lprovided with curved arms, D', which reach outnear to the margin of the disk, leaving a narrow rim or felloe, as shown in iig. 4. This disk is pivoted to a plate, E', and secured in position by the guides F, in which it slides upward and downward, for a purpose hereinafter shown. 4

.Ih'e practical use of this disk is as follows:

A. certain quantity of clay is put in the mould; Va spiral grooved core is then forced in, which presses the clay between the outside ofthe core and wall of the mould, which gives the thickness and shape of the4 bottle, The bottom is now put on, which consists of a disk of clay of the proper size and thickness. This is inserted in the large open end.A of the bottle. The disk is then slid up until it covers the openingof the mould and bottom of the bottle, against which it is pressed, and at the saine time given a rota-ting movement, the effect' of which is that a portion of the clay of the bottom will be forced'outward by the curved arms, pressing it, by this means, on and into the lower edges of the bottle, thereby uniting the bottom tothe bottle.

We are aware that disks have been and are used for this purpose, and for which a patent-was granted to us on the 31st day of July, 1847, but'the disks were 'provided with radial grooves, which ext-ended to the extreme margin ofthe disk, the consequence of which is, that on pressing them against the bottom of the bottle the k cla-y would be forced along the grooves' to' the edge of thedisk, and fall 0H, away from the bottle, instead of holding or retaining the Surplus-'clay at the'joint, so as tomake the union of the bottom to the' bottle tight and secure. But, by making -tbe disk with curvedurms lor grooves, andrhaving them terminate a. short distance from the margin, as above described, the surplus' clay is not driven or carried away, but-is retained about the joint bythe rim of the disk, in consequenpeof which it-is worked or kneaded into'the joint,.thereby making it more secure Saud complete than can be done with a disk provided with *radialv grooves, as above instnnced,- for a large percentage of-bottles -made with the radial groove-disk are lost, vi'n consequence of the bottom not being united to the bottle in a goodand substantial manner. l

What I claim as my'invention, anddesireto secure by :Letters Patent, is-' 1. The combination of the bar G, adjusting-stays a, roller'F, and bottle-mould, in the manner substantially as described.

2. The disk C', provided with curved or radi-a1 arms or grooves'D, terminating within a short distance of the margin of the disk, leaving a. rim around the lentire edge, for the purpose set forth. E. H. MERRILL, l H., E. MERRILL.
